RESUMEN
By the bioactivity technology of Low-Temperature Preparation of Anatase and Rutile Layers on porous Titanium Substrates, CPTi(Commercially pure titanium Phi4.0 mm x 20 mm) was processed and treated as experiment specimens while CPTi was treated as control specimens. Experiment specimens and control specimens were implanted into the holes (4.0 mm in diameter) in rabbit's right and left tibias respectively. After implantation for predetermined periods of 4,8,12, 16 weeks, the specimens were taken out with bone tissues, and were examined by a press-out tester to evaluate the shearing force between the implant and the bone tissue. It is found that the shearing force between the experiment specimen and the bone is more significantly higher than that between the control specimen and the bone, and the bonding time is shorter, the stabilization time is faster. This study has laid down a good foundation for the titanium metal's innovative applications in clinical orthopaedics.
